Answer» In the context of a hash function, a function for a single block of bits will be known as compression function. It is USED in cryptography and used for transforming two fixed LENGTH inputs into a fixed length OUTPUT. Encryption and decryption is used to encrypt or decrypt the data which need to be SECURED so that we use hash function,
